the answer to this question is "No!".
The 3ware stack of the raid units uses a 3ware specific format, compatible between 3ware models: 9500/9550/9650/9750.
The LSI MegaRaid used the LSI specific format, naturally not compatible to any other RAID controller brand...

ATA Identify word 76 bits 1-3 would show you the supported speed of your drive.
For example, the Intel SSD Toolbox could let you see that (Drive Details)...
I am sure some other tools could let you see those as well...

From what I learned over the years, it is common practice, for storage companies, to re-use returned drive that got 'fixed' we replacement drives when a drive under warranty fails in the field.
Unless it is specified in the contract that a failed drive will be replaced by a brand new one, they usually use a 'refurbished' drive that passed their tests.

Gentlemen,
Sorry to tell you that 3ware products before the 9650SE cannot support over 32bits LBA values (over 2 TiB or 2.2TB).
Also, none of the 3ware products would support 4kB sectors.
The 9550SX being old, there is no chance they will update its firmware since the product is EOL...
As far as I know, An Array could go over 2TiB but the OS needs to be able to support volumes > 2TiB to be able to access it.
Hope this helps!

The link is pointing to the 3.5" 6Gbs SAS drive, the proper link should be :

I got confised for a while!
Thanks!

Hi jump1e,
The 3ware 9550 PCI-X parallele bus would not support >2TB drives. However, it would support > 2TB raid units (multiple drives < 2TB)
Its firmware has not been updated up to the 9650/9750 raid controllers.
Also, this controller is NOT compatible with 32bit PCI bus, only on PCI-X bus. (was there a PCI 64 bit bus ?!)

I have 2 MB with X38 and X48 chipset, and I can't see any LSI 1st generation SAS 6Gb RAID controllers or HBA.
The LSI 1068E based SAS 3Gb seemed to works fine.
Some incompatibility... I am not sure what, but I gave up RAID on my system...
